I think you mean gluLookAt. Not all of those are represented by gluLookAt in quite that way. The first 3 parameters of gluLookAt is the position you are looking from, the next 3 are the point you are looking at, and the final 3 is the up vector.

I’m haven’t seen that exact terminology before, but depending on your point of view the first three or the 2nd set of three values in gluLookAt could be considered the reference point. (Is the reference point the point you are looking at, or the point you are looking from?)

The up view, would obviously be the last 3. I’m guessing the view plane normal is just the normal to the view plane so you would take the point you are looking at and subtract the point you are looking from to get that.
